Abstract

Coral reef associated gastropods diversity study was undertaken in Tuticorin group of islands (Hare, Vaan and Koswari). Underwater survey was made in three quadrants (10 sq.m) in each site. A sum of 40 species of gastropods were recorded from the study area. Most of the species are commonly found in three islands. Twelve were rare viz., Ficus ficus, Colubraria muricata, Casmaria erinaceus, Natica didyma, Nerita polita, Rapana bulbosa, Purpura rudolphi, Strombus sp., Architectonica perspectiva, Cypraea tigris, Cymatium lotorium and Haustellum haustellum were reported form the study area. Species diversity and richness were found to be higher in the Vaan island.

Abstract

Optimal reconfiguration of Radial Distribution System (RDS) is performed under the umbrella of Supervisory Control and Data Acquisition (SCADA) systems to achieve the best voltage and improved current profile with minimal kW losses. Significant amount of energy can be saved by reconfiguration of Radial Distribution Systems (RDS) without compromising radial nature of the system. However, due to inherent difficulty associated with RDS, it is often not possible to obtain an optimal solution using mathematical programming techniques. In this paper, an improved load flow algorithm with better computational efficiency is proposed for RDS solution. Another Computational algorithm is proposed to obtain optimally reconfigured RDS with improved voltage profile, minimal branch currents and minimal kW losses. The results obtained are compared with the other published papers to confirm the effectiveness of the proposed algorithm.

Keywords

Radial Distribution System (RDS), Voltage Deviation Index (VDI), Load Flow Program (LFP).

Abstract

Present experiments were conducted at the research farm of Indian Agricultural Research Institute, New Delhi during Kharif 1999 and Kharif 2001 to study the influence of nitrogenous fertilizer on the tilth of rice crop by remote sensing technique. Spectral radiance observations of the crop canopy were collected with the Portable Spectroradiometer which scanned from 330 nm to 1100 nm of electromagnetic spectrum range at 5nm interval (band-width). Normalized difference vegetation index was calculated for the both tillage practices, puddle and unpuddled situation at different growth stages for different fertilizer treatment. Fertilized plots were observed to have a higher value of BR than controlled ones throughout the crop growth period, both in puddled and unpuddled treatments. The higher values of band ratio were observed in puddled rice compared to the unpuddled rice irrespective of growth stages and fertilizer application levels. Statistical correlations were developed between NDVI (Normalized difference vegetation index) and RVI (Ratio vegetation index) with LAI (Leaf area index), DM (Dry matter) production and total leaf chlorophyll content. Second order polynomial equations were developed to correlate remotely sensed data with crop biometrics. Polynomial second order equations of 'band ratio' were found to be better fitted than NDVI with crop biometrics.

Abstract

The present study concerns with the abiotic parameters of sikrahana river water, located near motihari, the district head quarter of east champaran. The exact location of the spot is 84°43'48"E and 26°46'48"N. This analysis was carried out from January 2010 to December 2010. The abiotic parameters such as water temperature, turbidity, hardness, pH, alkalinity free CO₂, DO, BOD, COD, CHLORIDE, PHOSPHATE, SULPHATE etc. were analyzed during the present investigation. The data obtained from the analysis were compared with the data recommended for water quality standard by WHO and BIS.

Abstract

Flubendiamide is a recently introduced, fast-acting insecticide with an excellent residual effect. In an unpublished study, it was reported not to cause any genotoxic, carcinogenic and neurotoxic effects in mammals. However, recent studies suggest that it is toxic for fish and Chinese tiger frog. Alterations in leukogram, erythrocytic indices and aspartic acid concentration in cerebrospinal fluid in water buffalo following its chronic exposure to flubendiamide have also been recorded in our laboratory.

Abstract

Mobile has emerged as the technology whose spread has surpassed all predictions and records. After its successful use in trade, commerce and banking, it is applied in governance and agricultural extension. A number of initiatives like Kisan Call Centre (Toll free number-18001801551), Mobile portal (http://www.mkisan.gov.in), Voice SMS (http://www.iksl.net) has been taken to provide mobile-based services to the farmers. All these initiatives aim at empowering the farmers through agricultural information which the farmers are expected to apply for increasing productivity and profitability. A study was conducted in Jharkhand state of India to ascertain the application of agricultural information accessed through mobile. Data were collected from the purposively selected districts, one each from three agro- climatic zones of Jharkhand on the criteria of mobile user base. The findings revealed satisfactory level of information application. The selected independent variables viz., family education, social participation, extension contact, mass media and IT exposure, attitude towards mobile, annual agricultural income, information needs, knowledge about mobile feature, level of aspiration about mobile and monthly expenditure on mobile service were found positively and significantly correlated with information application at 1 per cent level of probability. Age was found negatively and significantly correlated at 1 per cent level of probability. However, innovation proneness was found positively and significantly correlated at 5 per cent level of probability. The selected independent variables could explain the variability upto 41.6 per cent whereas the variable information needs alone contributed upto 34.6 per cent. Hence, intervention like awareness programme should be undertaken so that felt needs could be expressed and unfelt needs could be converted into felt needs. Extension organizations need to provide more specific and personalized advice.

Abstract

Agro-pastoralism is the backbone for the sustenance of livelihood of people in semi-arid mountainous deserts of Ladakh, India. Livestock comprising sheep, goat, yak, donkey and horse, play an important role in human survival by providing fuel, transport, wool, milk, organic manure, meat and hide. Deficiency of fodder is the major constraint in livestock production system in this area; hence grassland vegetation availablefor grazing is important for livestock feeding and nutrition. The present study was aimed to evaluate grassland productivity in different villages of Leh, Ladakh. Productivity of grasslands in the study area ranged from 0.7 to 8.8 q/ha, reflecting low values and wide variability. Nutrient availability in grasses was poor, while fibre content was high. Supplementation of feed, fodder or concentrate ration is therefore essential to meet the nutritional requirements of the livestock largely dependent upon grazing in those grasslands.

Abstract

An effort has been made to deliver a complete assessment of the present advancement of the drone technology adopted by Coal India Limited (CIL) through CMPDI and its application in the coal mining industry. Nowadays, drone operations are gaining more and more attentions to ease out routine jobs in the mining industry and unveiling new arenas of opportunity. To name a few, 3D mapping of the mine environment by generating ortho-photo mosaic, blasting monitoring as well as postblast rock fragmentation measurements, inventory monitoring, survey of colonies and residential areas, monitoring of vegetation, settlement etc. been the new areas of interest. This paper offers an assessment of types of drone, their specifications, and specific applications of drones along with various sensors for mining applications. Possibilities of implementation of drone technology in underground mining conditions are also discussed.
